Whether you want to make your home more energy-efficient or just a cosier place in the winter, addressing thermal bridges should be your first port of call. Celotex TB4040 PIR Insulation 40mm is a BBA certified thermal insulation solution purposed to combat thermal-bridging in a variety of floor, wall and roof applications. The 2.4m x 1.2m boards are made with the environment in mind. Manufactured using polyisocyanurate and blowing agents with zero ozone depletion potential, the boards have zero ozone depletion potential (ODP) and low global warming potential (GWP); meaning they're as soft on the environment as they are hard on thermal bridges, boasting a thermal conductivity of just 0.022 W/m.K.
40mm Celotex PIR boards feature low emissivity foil facings that improve thermal conductivity in sealed cavity air spaces. Celotex TB4040 is also equipped with a BRE Green Guide rating A, which can be used in your BREEAM assessments to show environmental performance.

This Celotex insulation board features low emissivity foil facings and is manufactured from rigid polyisocyanurate (PIR) using a blend of blowing agents that have zero ozone depletion potential (zero ODP) and low global warming potential (GWP). Specifically designed to eliminate thermal bridges, (as the 'TB' in its title states), TB4040 is suitable for roof, floor, and wall applications in new buildings or refurbishment projects, giving improved thermal insulation performance within cavity air spaces. Its thermal conductivity of 0.022w W/mK makes it the ideal solution for insulation in pitched roofs, flat roofs, solid masonry walls, timber frames, and steel framed systems. It can also be used in solid floor systems such as screed and concrete slab floors, and as loft insulation between timber rafters.
Celotex TB4040 can be used in the following construction types:
The Celotex TB4000 range is a cost-effective alternative to brands such as Kingspan, without compromising performance. Celotex TB4040 multi-purpose insulation board is your one-stop solution when it comes to overcoming thermal bridging. Celotex 40mm TB4040 boards were developed as a simple solution to overcome localised thermal bridges by providing a continuous layer of rigid polyisocyanurate PIR insulation within the building structure.
Let's have a look at the specs:
BS EN is British and European Standard Specifications. With over 100 years of experience, the British Standards Institute is recognised as the UK’s National standards body.
Celotex is a leading British manufacturer of 40mm TB4000 PIR insulation. Founded in the early 1920s, the company has since evolved from a fibreboard insulation company to one that solely focuses on PIR insulation boards. The TB4040 insulation board is just one of many popular thermal insulation solutions in the Celotex product range. The Celotex TB4000 PIR insulation range consists of thicknesses: 20mm, 25mm, 30mm, and 40mm.
As they are super light and portable, 40mm Celotex TB4040 boards can also be handled and transported easily; making them a doddle to install. If you need to store 40mm Celotex TB4040 insulation boards for a while before installation, you should choose a cool, dry space.
Our rule of thumb when it comes to storage is that the boards should not be stored on the ground. Instead, pop them on a level surface and under a protective cover, just for good measure.

This insulation was used to address thermal bridging I had through some beams in our roof. Great to reduce localised heat losses in our loft. Also very competitive price!
